Figure 1 Therapeutic opportunities to block ErbB-2/HER-2 oncogenic signaling Normal mitogenic signaling (left) and Erb-2 (and presumably HER-2) signaling (right) is mediated by Cyclin D1 or other D-type Cyclins through activation of either Cdk4/6 kinases, kinase-independent interaction with Cdk4/6 and p27Kip1, or interaction with other targets. Boxes at the bottom indicate the main biological consequences of each pathway. Cancer Cell 2006 9, 2-4DOI: (10.1016/j.ccr.2005.12.026) Copyright © 2006 Elsevier Inc. Terms and Conditions
